Canyon County Mosquito Abatement District officials say another trap has tested positive for the West Nile Virus, the fifth of the season so far.  

The trap is located in western Canyon County south of Parma, close to the Boise River.  The trap was collected Thursday, July 28.

“The persistent hot temperatures of 100-plus degrees is causing a significant increase in the Culex mosquito species population and West Nile Virus activity,” accpording to Canyon County spokesman Joe Decker. “The Canyon County Mosquito Abatement District has been monitoring this increase and has responded accordingly with both mosquito larvae control operations along the Boise River near Parma and also night-time ULV ‘fogging’ operations over the past several days.”  

Experts say mosquito production sites are wading pools, small garden/ornamental ponds, and horse and other livestock water troughs that are algae covered or have been stagnant more than three days. The best defense against Culex pipiens, they say, is to refresh any water holding container or tank every three of four days.

The Canyon County Mosquito Abatement District also wants to remind everyone that the best defense to avoid mosquito bites is to wear an EPA approved insect repellent, preferably one containing 30% DEET.  It’s also important to avoid mosquito bites by following practices known as the “7 D’s”.

  • DRAIN any standing water on your property that may cause mosquitoes and remember do not over irrigate.
  • DAWN and DUSK are times to avoid outdoors.
  • DRESS appropriately by wearing long sleeve shirts and long pants when outdoors.
  • DEFEND yourself against mosquitoes by using an insect repellent.
  • DOOR and window screens should be in good conditions to prevent mosquitoes form entering your home.
  • DISTRICT personnel are here to help address mosquito problems that you may be experiencing.
